Role of DC Circuits in Smart Grids: An Overview

In contemporary energy systems, direct current (DC) very high or medium voltage-are being used more and more. This is because DC allows for more flexible management and can transfer and distribute electricity in situations when Dc circuits are either impossible to do so or are less affordable. From the earliest systems to the most recent power Ac and energy-source converter systems, this study gives a broad account of the development of high-current DC transport. It is detailed how voltage and electrical current methods operate and what is needed for modeling. In order to facilitate within -depth reading, the article includes multiple sources along with a brief overview of the cutting-edge in high-voltage direct Important advancements throughout the last 20 years are emphasized. The explanation of drivers in both politics and economy, as well as problems pertaining to functionality and direct current (DC) safeguarding.
